“I’ve been having pain since December, I grappled nine rounds
straight, the next day both shoulders blew up, inflammation and I’m
trying to get this thing taken care of,” Johnson wrote in an
Instagram post that was deleted after he underwent surgery.

Johnson last appeared at UFC 216, where he authored a 2017
“Submission of the Year” with a fifth-round armbar of Ray Borg to
break Anderson
Silva’s record for most consecutive successful title defenses.
“Mighty Mouse” is expected to defend his belt next against reigning
bantamweight champion T.J.
Dillashaw at some point in 2018. However, Johnson rejected a
proposed matchup with Dillashaw last year before targeting a
showdown with Borg.
